Coccolithophores are microscopic algae that first appeared 220 million years ago, and flourished during the cretaceous period. They produce peculiar plates called cocoliths out of calcium carbonate, and incorporate them into an external shell. They constantly remove carbon from the atmosphere as they die and sink to the ocean floor, producing chalk. This is an important feedback system in the global carbon cycle. Seriously, how does cellular machinery produce these structures? Life i...

Scanning electron micrograph of part of a thale cress flower, showing the male and female reproductive organs. The female part of the flower, the pistil (the blue feathery structure on an olive green stalk), is at the centre of the image and contains egg cells (ovules) housed in an ovary. It is surrounded by the male parts, the stamens, which have their anthers coloured light green and their filaments brown. Photography by Stefan Eberhard

"The micro-structure of a scale from a butterfly wing. Moth and butterfly wings use pigments to make some colours but physical structures, that affect the behaviour of light itself, to make others. The holes are around 1 micrometre across, about the size of a bacterium. Scanning electron microscopy by Dr Bronwen Cribb, University of Queensland."

Diatom . Diatoms are photosynthetic plankton (microscopic algae) ubiquitous in oceans and freshwater systems. They are a major source of nutrients for marine organisms as well as a major producer of oxygen. They have been dubbed the “lungs of the ocean,” producing about 20 % of the oxygen we breathe–as much as all the rainforests combined .

Diatoms are a major group of algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons, fans, zigzags, or stellate colonies.
